LAWN-MOWER ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 758,080, dated April26, 1904.

Application filed January 9, 1904.

tachments; and I do hereby declare that the' following is a full, clear,and exact description of the same.

This invention relates to harvesting machinery, and particularly to aclass thereunder known as lawn-mowers.

An object of this invention is to provide novel means for elevating thegrass in order that the cutter-blades may come in contact therewith, itbeing a well-known fact that the wheels of a lawn-mower press the grassinto such close contact with the ground that the blades or cutter of alawn-mower do not come into contact with the said grass. It also happenssometimes that the grass lies fiat on the ground from other causes andrequires a rake before it stands in position to be engaged by thecutting apparatus of a lawn-mower. It is therefore the object of thisinvention, as stated, to engage the grass and raise it from the ground.

Furthermore, an object of the invention is to provide novel means foradjusting the position of the attachment with relation to thelawn-mowerthat is, for retaining it in operative position or for holdingit in such position that it will not operate or interfere with the useof the lawn-mower in any way.

Furthermore, an object of the invention is to provide novel means foradjusting the position of the points of the attachment whereby the saidpoints may be raised or lowered with relationto the ground, means beingalso provided for retaining the attachment in the various adjustmentsmentioned.

Finally, an object of the invention is to provide a lawn-mower of thecharacter noted which will possess advantages in points of simplicityand durability, proving at the same time satisfactory in use andcomparatively inexpensive to produce and maintain.

With the foregoing and other objects in viewthe invention consists inthe details of construction and in the arrangement and com- Serial No.188,401. (No model.)

bination of parts to be hereinafter more fully set forth andspecifically claimed.

In describing the invention in detail refer ence will be had to theaccompanying drawings, forming part of this specification, wherein likecharacters denote corresponding parts throughout the several views, inwhich Figure 1 is a plan view of a lawn-mower with the attachmentapplied thereto. Fig. 2 is a sectional view on the line :20 w of Fig. 1.Fig. 3 is a similar view showing the attachment out of operativeposition. Fig. 4: is a perspective view of a fragment of the attachment.

In the drawings, 1 denotes an ordinary lawn-mower with a gear-casing 2on each end,

each of said gear-casings having on its inner facea rib 3, which iscurved longitudinally. A hook 4 is mounted on the face of each casingand is designed for the purpose of engaging the eye 5, carried by thehead 6 of the attachment.

The attachment resembles a rake in that it has a head6 and teeth 7, thesaid teeth being here shown as integral with the head, though theconstruction in this respect may be varied. The ends of the head arebent at right angles to the main portion, and each of the said ends hasa lug threaded to receive the adjustingscrew 9, the said adjusting-screwbeing provided to rest against the member 3 for the purpose of adjustingthe ends of the teeth of the attachment with relation to the ground, aswill be fully apparent from an inspection of Fig. 2. 'The ends of thehead are also provided with slots 10, which are slidable on the threadedstuds 11, which studs project from the inner faces of the gear casing.The studs 11 may be integral with the casing or they may consist ofbolts run through the casing, with the head of the bolt lying on theinside of the casing, but this being a detail of construction which neednot be dwelt upon.

As will be apparent from an inspection of Fig. 3, the attachment may beswung out of operative position, with the teeth thereof lying over thedividing bar and blades, in which position it will not interfere withthe operation as a lawn-mower of ordinary construction. Where the grassis tangled, however, and lies flat on the ground from any cause, theattachment will be used, for the reason that it accomplishes a desirableresult and one which will not be dispensed with after it has once beenemployed. By the use of the screw 9 the points of the teeth may beraised or lowered to suit the conditions of the ground over which themachine is to be operated, it being understood that where the groundisuneven or has obstructions of any kind the points of the teeth shouldbe considerably elevated,

while if the lawn is level and well kept the teeth might be made toassume an approximately horizontal position, as the said teeth arecurved slightly, so that the points always lie above the main portionsof the said teeth.

The construction, operation, and advantages will, it is thought, beunderstood from the foregoing description, it being noted that variouschanges may be resorted to in the proportions and details ofconstruction for successfully carrying the invention into practicewithout departing from its scope.

, Having fully described the invention, what I claim as new, and desireto secure by Letters Patent, is

1. In an attachment for lawn-mowers, the combination with the casings ofthe gearwheels each of which is provided with a "rib, a grass-liftingattachment hinged with relation to the casings, lugs connected to thegrassends of the said screws, substantially as described.

4. In an attachment for lawn-m0wers,a head having teeth, the ends of thehead being bent with relation to the main portion, lugs formed with thehead, adjusting screws threaded through the lugs, means for connectingthe ends of the head'to the lawn-mower and ribs against which the endsof the adj us ting-screws abut.

5. In a lawn-mower, suitable gear-casings, I

an attachment comprising a head and teeth, the ends of the head beingbent and formed with slots, studs in the slots by which the head ispivotally connected'to the lawn-mower, and eyes carried by the ends ofthe head and hooks for engaging the eyes.
